- The backplane mod is very easy. It can be done without removing the backplane.
-
- I am using an 030 board to drive a NextPrinter under 2.1,
- but have been unable to do this under 3.0.
-
- The headless 030 boots fine but panics when it tries to start WindowServer.
- Everything else works fine, but WindowServer is needed to run the printer :-(
-
- Has anyone succeeded in getting a headless Next to print under 3.0?
